I received an e-mailed press release from The Peanut Institute: Peanuts and Peanut Butter Support Women’s Health.

When it comes to health, women face unique challenges that call for unique nutrition. In fact, research has found that women face a higher risk of dying from heart disease than men,¹ and may be at risk for other conditions such as hypertension,² certain cancers,³ and even Alzheimer’s disease.⁴  To help women protect their health, The Peanut Institute is sharing information on the benefits that regular consumption of peanuts and peanut butter delivers to females at every stage of life.

Here are excerpts from those stages.

• Birth to 24 Months:  A child’s first two years are referred to as “B24” and are a critical time in the growth and development of the brain and body. The most recent Dietary Guidelines for Americans highlights peanuts as “an important source of iron, zinc, protein, choline and long chain polyunsaturated fatty acids.”²
• For youngsters and teens: On the subject of protein, at 7 grams per ounce, peanuts have more protein than any other nut.^6. That’s especially important for girls who work out since protein helps muscles grow, recover and stay healthy.⁷ Plus, peanuts are satisfying and an easy, on-the-go snack that can be stowed in a backpack, locker or car.
• For adults and seniors: The Journal of the American Heart Association found that following a plant-based diet with nuts, legumes, fruits and veggies can lower the risk of dying prematurely from multiple causes, including cardiovascular disease, one of the leading causes of death worldwide.⁸ In addition, phytosterols, like those found in peanuts, may inhibit the growth of cancers that affect millions of women, including lung, stomach, ovarian, colon and breast cancers.^9-12

I did not look to see whether the references were funded by the peanut industry, but there is plenty of precedent.  See, for example,

• Industry-funded study of the week: Peanuts
• Annals of industry-funded research: Peanuts this time
• Industry-funded request of the week: prove peanuts healthy

But there’s more.  A reader, Monica Baer, sent me another press release from the Peanut Institute: New Gut Microbiome Research Points to Positive Impact on Memory and Mood from Peanut Consumption

Research from the University of Barcelona on the gut microbiota has found that daily consumption of peanuts and peanut butter can produce compounds in the gut that help improve memory and reduce stress response, including anxiety and depression, in healthy young adults. Findings from the ARISTOTLE study were published online in the Journal of Functional Foods this September and shared by The Peanut Institute. 

I did look up this one: Isabella Parilli-Moser, Ricardo López-Solís, Inés Domínguez-López, Anna Vallverdú-Queralt, Sara Hurtado-Barroso, Rosa M Lamuela-Raventós, Consumption of peanut products enhances the production of microbial phenolic metabolites related with memory and stress response: Results from the ARISTOTLE trial, Journal of Functional Foods, Volume 108, 2023, 105746, https://doi.org/10.1016/j.jff.2023.105746.

Funding: This work was supported by funding from the Peanut Institute.

I like peanuts.  They are legumes and real foods.  But to attribute overall health and memory function to eating peanuts seems a bit far-fetched.  That’s why the Peanut Institute is funding research: to convince you peanuts are a superfood.  There is, of course, no such thing.  Superfood is a marketing term.  Should you eat peanuts?  Sure.  Why not?

I received an emailed announcement alerting me to today’s big event: It’s National Peanut Brittle Day, “a day dedicated to honoring one of our favorite uniquely American treats.”

Who knew?

The press release continues with some not-so-sweet news:  peanut brittle is yet another victim of inflation.

The chart shows the cost of the raw ingredients in peanut brittle has increased by nearly 18% — from just under $0.38 per pound in early 2021 to nearly $0.46 cents today.

Other cost increases: transportation, energy, labor add up to “a recipe for expensive candy!”

A strange press release, but an interesting commentary on what’s happening with prices.

The press release: New Research Finds Consumption of Peanuts Supports Weight Loss, Lowers Blood Pressure and Improves Glucose Levels

The Study: Petersen, K.S.; Murphy, J.; Whitbread, J.; Clifton, P.M.; Keogh, J.B. The Effect of a Peanut-Enriched Weight Loss Diet Compared to a Low-Fat Weight Loss Diet on Body Weight, Blood Pressure, and Glycemic Control: A Randomized Controlled Trial. Nutrients 2022, 14, 2986. https://doi.org/10.3390/nu14142986.

Conclusion: Intake of 35 g of peanuts prior to two main meals per day, in the context of an energy-restricted diet, resulted in weight loss comparable to a traditional low-fat weight loss diet without preloads. Greater systolic blood pressure reductions were observed with peanut intake, which may lower cardiovascular disease risk.

Funding: This research was funded by The Peanut Institute…The funder had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.

Conflicts of Interest: J.B.K., P.M.C. and K.S.P. received a grant from The Peanut Institute to conduct this study. The funder had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.

Comment: The funder had no role?  That’s what they all say.  That may be true in this instance, but but much research demonstrates otherwise, and funders are unlikely to pay for studies that might give them unfavorable results.

The underlying purpose of this study was to demonstrate that if you are on a weight-loss diet, you can eat lots of peanuts and still lose weight: “70 g/d of peanuts may be included in an energy-restricted weight loss diet without attenuating weight loss over a 6-month period.”  Of course you can, if you stick to a low-calorie diet.

I’m all for eating nuts.  Substituting them for ultra-processed snack foods is a reasonable approach to dieting, but don’t expect to lose any more weight eating nuts than from any other source of calories.  This is a marketing study, aimed at encouraging you to eat more peanuts.

Really?  Another peanut butter Salmonella recall?  The last one was a disaster (more than 700 cases of illness and 9 deaths).  Among other things, it resulted in imprisonment for the head of the Peanut Corporation of America.

Well, here we go again.

The FDA announced the outbreak traced to Smucker’s Jif.

It also announced Smucker’s recall of those products.

And it provided links to further information.

• What is Salmonella
• Food Safety Tips for Consumers & Retailers During an Outbreak
• Who to Contact

The CDC announced its investigation results to date.

• Illnesses: 16
• Hospitalizations: 2
• Deaths: 0
• States: 12
• Recall: Yes
• Investigation status: Active

And it issued a food safety alert. Peanut butter has a long shelf life.  Discard Jif peanut butter with lot code numbers 1274425 through 2140425, with “425” at the end of the first 7 numbers.

But that’s not all.  Companies using Jif peanut butter dip with precut vegetables or in candy were also in trouble (see list at the end).

How does Salmonella get into peanut butter?  Scientific American explained how this happened the last time.

Feces from some animal is a strong possibility. A leak in the roof, for example, caused one of the early outbreaks. How salmonella got into the water that was on the roof, no one knows for sure. Maybe birds, for instance, which accumulate around peanut butter processing plants.  The roasting of peanuts is the only step that will kill the salmonella. If contamination occurs after the roasting process, the game is over and salmonella is going to survive. Studies have shown that salmonella can survive for many months in peanut butter once it’s present.

Preventive controls, anyone?

I recently received a letter (with my emphasis) making the rounds from the research director at The Peanut Institute (yes, such places exist):

Dear Colleague….

The Peanut Institute Foundation is a non-profit 501 (C)(3) entity that funds research in the area of peanut nutrition. We are requesting proposals from researchers across the country to enhance our understanding of how consuming peanuts, peanut butter, and peanut products improves health in various populations (eg. immune health, personalized nutrition, gut microbiome, brain health, chronic diseases, diet quality, etc.).

Suggested funding amount: $25,000 – $250,000

Deadline for submission: March 26, 2021

To download an application, visit: https://peanut-institute.com/nutrition-research/peanut-nutrition-grant-2021/

This is a classic example of how industry-funded research gets aimed at marketing, not science.  If the Peanut Institute were interested in science, it would request open-ended proposals about whether peanuts—as opposed to any other nut or legume—have any particular effect on health.  Big difference.

The Peanut Institute wants evidence of benefits.  It will not fund proposals unlikely to demonstrate benefits.

This is about marketing, not science.

And while we are on the subject of peanuts

Take a look at this Civil Eats’ superb investigative report on Big Peanut (yes, this too exists): “The Peanut Industry Has a Monopoly Problem—but Farmers Are Pushing Back.  Two shelling companies buy 80 percent of the nation’s peanut crop each year, allowing them to drive prices down while costing U.S. taxpayers millions in subsidies.

the peanut shelling industry is dominated by two powerful companies that together buy 80 percent of all peanuts grown in the U.S. The two companies, Golden Peanut and Birdsong, operate massive shelling facilities throughout the peanut belt, and together control or outright own nearly 200 buying points, where farmers must go to sell their raw peanuts. The system isn’t just unfair—it’s wildly expensive. Subsidizing the peanut industry cost U.S. taxpayers more than $2 billion from 2014 through 2018. It’ s the most costly per-acre crop to taxpayers in America, in large part because monopoly power controls pricing in the industry….For many growers, Birdsong and Golden are the only options, so they take whatever price the big shellers offer. Before 2002, growers received a more than $600-per-ton price guarantee; now that’s been replaced with a marketing loan system that guarantees just half that.

Looks like this industry could use even more scrutiny.

The Peanut Institute is working overtime to convince you to eat more peanuts.

Disclaimer: I love peanuts and think they are great to cook with and make an excellent snack—peanut butter too—but I see no need to overhype them, as this press release does.

Research Reveals Daily Dose of Peanuts Delivers Body and Mind Benefits: Americans Encouraged to Pause for Peanuts…Peanuts are a superfood so just a small amount can fend off mid-morning hunger, help eliminate the afternoon slump and deliver much-needed brainpower.

“Superfood,” I must remind you, is a marketing term.  It has no nutritional meaning.  All fruits, vegetables, grains, beans, and, yes, nuts, have nutritional value.  On that basis, all plant foods are “superfoods.”

The press release makes these claims, and provides references for most of them:

• Regular peanut consumption has been associated with a reduced risk of heart disease, diabetes and numerous kinds of cancer.
• An ounce of peanuts packs more protein than any other nut.
• Peanuts stimulate peptide YY, a hormone that decreases appetite.
• Peanuts also have a low glycemic index that helps stabilize blood sugar to prevent the feeling of ‘crashing’ in the afternoon.
•  A single serving of peanuts is packed with 19 vitamins and minerals, including the antioxidant resveratrol, which has been shown to increase blood flow to the brain.
• Peanuts also contain high levels of niacin and are a good source of vitamin E – two nutrients that support brain health and have long been known to protect against Alzheimer’s disease and age-related cognitive decline
• Eating peanuts twice a week can reduce the risk of premature death by 12% and reduce the risk for certain cancers, including colorectal, gastric, pancreatic and lung cancers.
• Regular consumption can also reduce the risk of death due to heart disease by 24%, respiratory disease by 16%, infections by 32% and kidney disease by 48%.

As I read the research on peanuts, it associates eating nuts of all types with good health.   Is there something distinctive about peanuts as compared to other kinds of nuts?

I doubt it—all nuts are worth eating.

A basic prinicple of nutrition is to vary food intake.  You love peanuts (as I do)?  Eat them, but go easy on the salt.

Peanuts are delicious when freshly roasted—I always keep some on hand—and they are highly nutritious, despite their calories.

But the peanut industry must not think sales are high enough (oh those sales-inhibiting peanut allergies).

Its trade group, The Peanut Institute, has issued a Call for Research Proposals.

We are currently requesting human peanut nutrition research proposals with an emphasis on the effect of consuming peanuts, peanut butter, and other peanut products on: (1) cognition/brain health, (2) chronic disease risk and outcomes, (3) diet quality, and (4) gut microbiome in various populations. Other research areas that increase the understanding of peanut consumption and human health are encouraged. All novel and noteworthy proposals that advance the health and wellness message of peanuts will be reviewed [my emphasis].

The Peanut Institute is not interested in funding open-ended research exploring the effects of peanuts on health.

Instead, it intends only to consider proposals designed to prove benefits.  This is marketing research, not basic science.

As I demonstrated in Unsavory Truth: How Food Companies Skew the Science of What We Eat, the basic observation is this: industry-funded research almost always favors the sponsor’s product.

I discuss similar requests from other trade groups in that book.  Guess what.  The funders usually get what they ask for.

I was interested to see the FDA’s announcement that it “acknowledges” and will “exercise enforcement discretion” (translation: will not oppose) a qualified health claim linking the early introduction of peanuts into the diets of young children with severe eczema or egg allergies as a means to reduce their risk of peanut allergy.

Here’s the claim, which the FDA says manufacturers can use right away:

For most infants with severe eczema and/or egg allergy who are already eating solid foods, introducing foods containing ground peanuts between 4 and 10 months of age and continuing consumption may reduce the risk of developing peanut allergy by 5 years of age. FDA has determined, however, that the evidence supporting this claim is limited to one study. If your infant has severe eczema and/or egg allergy, check with your infant’s healthcare provider before feeding foods containing ground peanuts.

The FDA’s decision is based on:

• That one study, which I’ve written about in two previous posts (see here and here).
• Epidemiological evidence on the increasing prevalence of peanut allergies among U.S. children
• Recommendations of pediatric authorities, particularly the 2017 Addendum Guidelines for the Prevention of Peanut Allergy in the United States.

But why a qualified health claim?  Whenever you see one, you know that business interests are at stake.

In this case, the claim is in response to a petition filed by Assured Bites, Inc., maker of Hello Peanut products.  Check the astonishing prices of these products and you can see why this company wanted a health claim, and why it is already advertising it.

Really, you can do this at home.  We are talking here about starting high-risk kids out—under medical supervision—with a small taste of plain, ordinary peanut butter.

The FDA allows qualified health claims because industry wants them for marketing and pressures Congress to force the FDA to allow them.

What’s wrong with qualified health claims?  The qualifications get lost in the marketing.  Parents may think Hello Peanut works better than much less expensive alternatives.
